The instructions from the Gmail setting page have now changed and say to tap 'Gmail' however on other parts of the Google Sync website, it says they will still allow connections through the Exchange tab on Business Google Apps account

I wasn't sure if one way was better than the other, what do you fellow members recommend?

I prefer installing the apps since the signature control and search are better. You still need the sync for contacts and calendars, but disable the email there. The newest GMail app on iOS has push notification.
